Is this still an issue?
I can see that the images in the guide reflect the 2022 series

also the metadata is correct for the 2022 series
It is important when recording is that you have recordings into a separate TV Shows Recording library from your normal TV Shows library
There was an issue where we lost the EPG metadata after recordings and this has just been corrected in the latest Plex Media Server beta - 1.29.1
- (DVR) EPG data might be lost for new recordings
